Recent replication crises in psychology and other fields have led to intense reflection about the validity of common research practices. Much of this reflection has focussed on reporting standards, and how they may be related to the questionable research practices that could underlie a high proportion of irreproducible findings in the published record. As a developing field, it is particularly important for Experimental Philosophy to avoid some of the pitfalls that have beset other disciplines. To this end, here we provide (...) a detailed, comprehensive assessment of current reporting practices in Experimental Philosophy. We focus on the quality of statistical reporting and the disclosure of information about study methodology. We assess all the articles using quantitative methods that were published over the years 2013–2016 in 29 leading philosophy journals. We find that null hypothesis significance testing is the prevalent statistical practice in Experimental Philosophy, although relying solely on this approach has been criticised in the psychological literature. To augment this approach, various additional measures have become commonplace in other fields, but we find that Experimental Philosophy has adopted these only partially: 53% of the papers report an effect size, 28% confidence intervals, 1% examined prospective statistical power and 5% report observed statistical power. Importantly, we find no direct relation between an article’s reporting quality and its impact. We conclude with recommendations for authors, reviewers and editors in Experimental Philosophy, to facilitate making research statistically-transparent and reproducible. (shrink)

Human consciousness is one of the greatest mysteries in the universe. From one point of view this should be surprising, since we know a great deal about consciousness from our own experience. One could say that our own conscious experience is the thing in the world that we know best. Descartes wanted to build the entirety of natural science on the foundation of our understanding of our conscious thought. Yet despite our intimate relationship with our own consciousness experience, from another (...) point of view consciousness is a puzzling phenomenon. We have no idea what it is about us, as physical beings, that makes us conscious, why we have consciousness, or which creatures other than humans have consciousness. Not only is it hard to answer these questions, it is hard to know how to even start to find answers. (shrink)

Irrelevant emotional stimuli often capture attention, disrupting ongoing cognitive processes. In two experiments, we examined whether availability of rewards can prevent...
